Essential Linux Skills Every Beginner Must Master

Most websites, services, and games run on Linux; once you understand one distribution’s core architecture and design principles, the rest become intuitive, so beginners should start with CentOS or RHEL.

For newcomers, videos are time‑consuming, forum posts are scattered, and books provide a systematic learning path; the author recommends the book Linux就该这么学 and practicing on a Linux virtual machine.

Key knowledge areas to master include:

Understanding the Linux Filesystem Hierarchy (FHS) and overall architecture.

Memorizing about 60 common Linux commands and mounting basics.

TCP/IP fundamentals and network configuration.

SSH principles and usage.

Basic firewall configuration with iptables.

Essential beginner tools and skills:

Vim editor for editing configuration files and scripts.

Git version control for managing scripts and code, crucial for DevOps.

Shell scripting for automation; Python is suggested later for advanced scripting.

After covering roughly 80% of these topics, you’ll have a solid foundation and should also learn basic hardware concepts such as memory types, CPU specifications, and networking equipment, which are vital for operations engineers.

Advanced “soft” knowledge includes building common services (file sharing, Git, databases, web servers, DHCP, etc.) using official tutorials, noting that installation steps may vary across Linux distributions.

Finally, the author emphasizes the growing importance of DevOps and automation, recommending learning a development language—Python is the preferred choice for modern Linux operations.
